I-69 runs straight through Davison Township, and everything to either side of it — the shops, the drives, the wide gravel aprons — takes a beating from a Genesee County freeze and thaw. ATB Construction Services LLC works that ground in both halves of the year, mowing and trimming while it is green and plowing it back open when it is not. Winter here arrives on the wind rather than off a lake: quick clippers that drop a few inches overnight and leave pavement slick well before sunrise. Summer has the opposite temperament, long and humid, grass climbing after every thunderstorm. Their answer to both is the same — get there, do it cleanly, leave the place usable.
